getting an intersection of 2 lines

[IdoBrickner]

Hello,

I am trying to get the coordinates of an intersection of 2 lines.
At first I want to do it very simple, later on I want to get the lines information from dxf.

I tried the following code:

from ezdxf.math import Vec2, intersection_line_line_2d

line1_start = Vec2(1, 1)
line1_end = Vec2(4, 4)
line2_start = Vec2(1, 3)
line2_end = Vec2(4, 2)

intersection_point = intersection_line_line_2d(line1_start, line1_end, line2_start, line2_end)

and getting the following error:

---> 10 intersection_point = intersection_line_line_2d(line1_start, line1_end, line2_start, line2_end)

File src\ezdxf\acc\construct.pyx:56, in ezdxf.acc.construct.intersection_line_line_2d()

TypeError: must be real number, not ezdxf.acc.vector.Vec2

please advise.

The intersection_line_line_2d() function expects a sequence of points for each line:

from ezdxf.math import Vec2, intersection_line_line_2d

line1_start = Vec2(1, 1)
line1_end = Vec2(4, 4)
line2_start = Vec2(1, 3)
line2_end = Vec2(4, 2)

line1 = (line1_start, line1_end)
line2 = (line2_start, line2_end)
intersection_point = intersection_line_line_2d(line1, line2)
